Firestone Water Block Sealant

Firestone Water Block available to buy online from AquaLiners Direct

Firestone Water Block is used to seal up edges and provide additional protection from water getting in behind the pond or lake liner where the seal will be under continuous compression.

It is specifically recommended for sealing behind termination bars when vertically fixing pond liner to a wall, and for around the inner edge of Pipe Flashing where it fits around a pipe. Water Block comes in tubes for use with a mastic gun making it easy to apply accurately where required.

Firestone Water Block, although safe for aquatic, animal and humans, is a solvent based sealant and should therefore be used with care. We would recommend you read through the Water Block Technical Information Sheet prior to use; this covers all safety precautions to take and full instructions for use.
